Can You Wear a Suit Without a Tie? When It Works and When It's a Mistake

By Randy Willard

Can you wear a suit without a tie? Yes, if it's the right suit. A casual summer suit with an interesting shirt says open collar. A business suit with a plain shirt says finish me, and skipping the tie there is one of the most common mistakes I see.

Tie or no tie: I love this conversation. You see the tieless suit everywhere right now. It's the hot look. But the suit, not the trend, should make the call. Neckwear is underrated, and there's a time to wear it and a time not to.

Randy's rule: A business suit worn open collar is like an amazing car on basic aluminum wheels. It looks cool, but you didn't finish it.

Tie or no tie: the quick guide

Why a business suit needs a tie

A lot of men put on a corporate suit, say a gray pinstripe, and wear it open collar for whatever the occasion. Big mistake. Don't do it.

It's the amazing car on basic aluminum wheels. The suit is presenting itself as a statement piece, and you didn't finish it. Worse, you look like someone forced you to come out and dress tonight and you got away without wearing a tie.

Put the neckwear on and it gives you a strong confidence, the kind the suit was asking for. It finishes the story of what that suit is about. It also tells people you know what you're doing and you're not afraid of dressing.

The plain shirt rule

The second test is the shirt. If you're wearing a subdued shirt (white, ivory, blue, medium blue, even a soft pink), you need neckwear to finish the look. A plain shirt and no tie under a suit just looks like something is missing.

For a corporate gray suit, keep it clean: a white shirt and a tie that accents the pinstripe. A professional statement, not over the top. Wear a suit tie, but skip anything too glossy or formal-looking; too much sheen takes away from the seriousness of a business suit.

When open collar is the right call

Some suits want an open collar. One of my favorites is a casual summer suit with trousers that have no belt loops and a two-inch waistband, a very modern style. The whole thing says open collar, no tie.

The key is what goes underneath. A more interesting shirt with an open collar on a casual suit is a good look. A plain dress shirt with no tie on a business suit is not.

But don't be too quick to leave the neckwear out, even in summer. Anybody can wear an open-collared shirt. With my desert tan summer suit, I wear a candy-stripe shirt and a tie chosen so it doesn't fight everything else but still gives you that summer vibe. A summer suit is also where you can have fun with neckwear: a floral or patterned tie that picks up the color of the suit, even the tones of the buttons, in a more relaxed, younger vibe. The tie reflects the personality of your day.

The same logic decides which suits to own. If you want the open-collar look, buy a suit made for it, like a lighter gray or a summer blue, instead of stripping the tie off your business suit. I walk through the five suits every CEO needs in my free CEO Masterclass.

Pick a collar made for no tie

Skip the tie and your collar becomes the detail everyone sees.

• English spread. When I wear a shirt open collar, the English spread works beautifully because it fans to the side and gives you that relaxed look. It's a powerful look on a square jaw like mine; if you have a rounder face, shy away from it.
• Button-down. It keeps your collar from flying away. I wear it under a sport coat, never a suit.
• European collar. A smaller collar for when you're dressed casually without a jacket.
• Semi-spread and medium spread. The classics for wearing with a tie. The semi-spread shows off the knot better, and it's my everyday choice.

Let the tie decide your shoes

Here's a simple rule of thumb that applies the majority of the time. If you're wearing neckwear, wear a lace-up: a brogue or another lace-up dress shoe finishes the dressier look. Take the neckwear off and you can wear a slip-on or a loafer, for a look that's halfway dressed up.

The tie also explains business casual. Business casual isn't just putting on a sport coat. It's when you're not in a tie and not dolled up, but you still look professional: a sport coat, a gentleman's gray dress trouser, a shirt with some color, a pocket square that picks up a third color, and a slip-on.

If you wear a tie, let it ride along

Putting on a tie is where the mistakes start to happen fast. Three things to remember.

A suit tie and a sport coat tie aren't the same tie. A sport coat usually has a pattern running through it, a windowpane or a houndstooth, and the trousers don't match the jacket. So I pair it with a solid tie in cotton or a woven, with a little texture and a flatter finish, neutral and along for the ride. A suit tie has a smoother, dressier finish with a little shine. Never put that shiny, silky suit tie on a casual sport coat look.

Match the tie to the shirt. With a candy-stripe or check shirt, don't grab a busy patterned tie or the outfit becomes a train wreck. Reach for a subtle design with some texture. And be careful when someone at home starts matching colors for you. As a stylist, I'm looking for a third color that takes the whole look into the wow category, not something monochromatic.

Keep it simple. Don't turn the tie into the subject. Let the suit style itself; the tie is along for the ride.

Details decide how the room reads you

Neckwear, collar, pocket square: these details matter in every outfit you put together, and they're what most men get wrong. Getting them right is exactly what sets you apart.

Frequently asked questions

Is it unprofessional to wear a suit without a tie?
With a business suit, yes, it usually looks unfinished. With a casual summer suit and an interesting shirt, an open collar is the right look.

Can I wear a suit without a tie to an interview?
Wear the tie. An interview calls for a business suit, and a business suit looks finished with neckwear.

Can I wear a suit without a tie to a wedding?
It depends on the suit and the dress code. A light gray suit looks its best at a summer wedding with neckwear. A casual summer suit with an interesting shirt can go open collar at a relaxed wedding. If the invitation says black tie, wear a tuxedo; if it says black tie optional, a black suit with a bow tie, a regular tie or an open collar all work.

What shirt should I wear with a suit and no tie?
Something with more interest than a plain dress shirt, with a collar that holds its shape open, like an English spread.

Should my tie match my suit?
No. It should support the suit without competing with it. Look for a third color that lifts the outfit rather than matching everything.

Can you wear a sport coat without a tie?
Yes. A sport coat without a tie is what business casual really means. If you do wear a tie with one, choose a solid with texture and a flat finish, never a shiny suit tie.

What shoes go with a suit and no tie?
Without a tie you can wear a loafer or another slip-on. With a tie, wear a lace-up dress shoe or a brogue.
